Hadith 688:3
'Abd al-Rahman narrated to us, Ziyad Abu 'Umar narrated to us, from al-Hasan, from 'Ammar ibn Yasir, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "The likeness of my nation is like the rain; it is not known whether its beginning is better or its end."
حدثنا عبد الرحمن، حدثنا زياد أبو عمر، عن الحسن، عن عمار بن ياسر قال: قال رسول الله صلى الله عليه وسلم: " مثل أمتي مثل المطر لا يدرى أوله خير أم آخره "
